PUME'ING APPARATUS.

To all whom t may concern: 1

Be it known that I, WILLIAM BENTON ROBINSON,v a ycitizen of the UnitedY States, residing at Easley, in the county of Pickens and State fof South Carolina, have invented certain newv and useful Improvements in Pumping Apparatusof which the following is a specification.V s Y' This invention has relation to wellpumpingrapparatus, and has for an object to 1 providev an apparatus intended to be placed in the bottom of a well, and embodying means operable to force the water upward to the level of the ground. Y

Another Object of the invention is to pro a videl a novel mechanism for automatically .closing `and openinga valve forming a part Y of my apparatus.

In addition to the .foregoingmy invention comprehends improvements in the details of construction andV arrangement of parts to be hereinafter morel fully described .andv particularly set forth in the appended claims.

Ylln the accompanying drawings in which similar and corresponding' parts are desig- Knated by the same charactersfof reference i throughout the several views in'which they appear A Figure Y 1, is a view in vertical sectionof afwell pumping apparatus constructed after the manner Yof my invention, illustrating the same as located in the bottom of a well. 'Y Fig. 2,'isav detail view in section illustrating the `valve operating mechanism, taken on the line 2-2 of Fig. 1.

Fig. 3, is a' view in plan'of the valve operating mechanism, and

Fig. 4, is a detail view in plan of the valve. l

vWith reference to the drawings 10 indicates a cylindrical casing disposed vertically and located in the bottom of a well, the casing being preferably Ysupported in. an outer casing 11 inclosing the lower portion of the'casing 10. The casing 10 is closed at itsu-pper end as indicated at 12 Yand is provided in its side wall adjacent its upper end with an opening 13;

A vcylindrical brasslining 14 is provided on the inner sideof the casing 10 adjacent the lower portion thereof, and a. piston indicated generally at 15' is provided for movement within the casing and for engagement with the lining wherebyV a smooth surface is provided'.V VThe piston comprises a discous.

and lowerY sides and adjacent `its periphery Y with flexible Vgaskets 17 V which extend raf dially beyond the'edge of the body portion of the piston for engagingthe liningflll. Annular rings 18 are applied to the gaskets and secured tothe body portion of the piston for holding the gaskets in place.

The body portion of the piston isformed with an openingV 19 adapted to be valve controlled, and to that end a disk 2O having an offset iange 21 is placed above said opening and secured by means of its liange tothe edge of the opening through the medium of bolts 22. The disk 2O is provided with a. plurality of radial openings 23 and a central Frou. i

opening 24 through which the lower end of A a vertically extending valve rod 25 projects. A valve is provided in the formVA of aY disk 26 which is applied to the under side of the disk 20 and is formed with radial openings 27 corresponding in shape and size to the `openings 23. A plate 28 is applied to the `underside of the valve 26 and is secured by Ameans of a peripheral flange'to the under side of the Vdisk 2O whereby the plate is sup-v ported for rotation between the plates 20 and 28. The lower plate 28 is similarly pro vided with radial openings 29 and a central opening through which the valvek stem projects a nut being preferably provided to said projecting end of thevalve rod.V

The valve rod 25 is supported ata point i intermediatel its length in a bearing 30 having alaterally projecting arm 31 formed with a longitudinally extending slot 32. A

one side Wall of the casing 10 and isadapted Ato beconnected to the arm 31 by means of 'standard 33 is extended Vhorizontally from arm 31 is formed with oppositely extending 1 arms which extend atan angle to the valve rod and are provided on their extremities .with rollers 35. The upper arm is indicated at 36'and the lower at 37. An arm 38 is adjustably connected to the upper end of the valve rod through the medium of a collar- 39 formed on said karm and through which collar the valveV rod projects. a set screw 40 provided on the collar serving to retainV the arm in adjusted position'. The outer extremity of the arm 38 is provided with a cam 42 sjldjllstably GOIlllcted `tothe valve rod at a point below the arm 38 and isprovided with a cam member 43 disposed at an angle relative to the'valve rod and at'right angles to the direction of inclination of the cam member 5l, the arm42 vbeing disposed diametrically opposite the arm 38. The cam member 13 is located also in a vertical plane coincident with the .plane of the roller 35 of the arm 37.V

vA piston rod 44 is connected at its lower end to the piston 15 centrally'thereo with its upper end projecting through a central opening in the :cover 12, a collar 45 adjustably secured to the piston rod abutting` against the under side ofthe cover to limit upwardmovement of the piston, Apostel?) 4is erected upon the cap 12 exteriorly .of vthe casing 10 to support ,at its upperend a pulley 4T aroundwhich a flexible element 48 passes, withv one .end of saidelement connectcdto the piston rod as at 49, and the opposite lend provided with an adjustable weight 50 to oounterloalance the weight .of the piston and appurtenant parts.

A stand pipe 51 is located in the well with one end in communication with the casing 10 at the botomthereof, and the opposite end -located at the vsurface of the ground.- A checkvalve '52, is interposed in the stand'pipe adjacent its lower end lrto prevent flow of water' in the pipe in a downwarddirection, a manually operable valve 53 Vloeing provided in the stand pipe adjacent'its upper end. The piston rod 44 is formed with an extension 50 .which extends upward and is connected to an operating leverl fulcrumed upon any convenient` stationary Vsupport whereby the piston rod and piston may be reclprocated. Y Y

In operation, and assuming the part-s to be in the position shown in Fig. 1', the water will flow from the well through the opening 13 into the upper portion of Athe casing V10 and will accumulate' abovev the iston. It will be remembered that the Cisk valve .26 isV in such a position as to dispose its radial openings 27 out of alinernent with the openings in the disks disposed above Vand below. Downward pressure is now appiston has reached its extreme' lowermost position, the cam member will ride over the pulley thereby partially rotating the valve rod to rotate the'disk valve 26 to dispose its openings in registration with the openings in the disks located thereabove and below.

VThe interior of the casing lO'above Yand below the piston Vhaving thus been placed in Y communication the piston fisV now moving upward, the water being displaced from one side `of the piston to the other .until the lower cam member t3 engages "the roller 35 ofthe` lower arm 37- whereupon'partialpro- ,Y v

tation Vof the valve rod will take place Vto rotate the disk valve -26 thereby movingthe same to' closed position. When theV '1119137.61' portion of the casing ldisagain filled a repetition of the foregoing operation will take place. Y

fhile I have illustratedv and described i my invention with some degree of particu-V la.rity,'1 realize thatinV practice various ailterations thereover *may "be mad'e, I therefore desire to reserve `the right and privilege of changing the form oftheV details of construction, or' otherwise altering the arrangement of the correlated parts without departing from the :spirit ofthe invention or the scope of the appended claims.V Y Y A' Y Havingy thusV described my" invention, what I claim as new and desire to secure'by Letters Patent is 1.
